Adapter for airsoft gun

Abstract

An adapter for airsoft guns includes a housing comprising a single, integrally formed plastic element, the housing having an upper portion configured to mate with a magazine well of the airsoft gun, an air reservoir located within the housing for holding pressurized gas, an air inlet configured for allowing ingress of pressurized air from an attached gas canister, an air outlet configured for allowing egress of pressurized air from the air reservoir, a piston valve between the air reservoir and the air outlet configured for preventing airflow from the air reservoir to the air outlet when in the rest position, and allowing temporary airflow from the air reservoir to the air outlet when contacted by a firing pin of the airsoft gun, a projectile inlet configured for allowing ingress of projectiles from an attached projectile magazine, and a projectile outlet configured for allowing egress of projectiles to the airsoft gun.

       7. The adapter for an airsoft gun of  claim 6 , wherein the piston valve comprises a spring configured to keep the piston valve in the rest position. 
     
     
       8. The adapter for an airsoft gun of  claim 7 , further comprising a bottleneck passage between the air reservoir and the air outlet, wherein the piston valve rests within the bottleneck when in the rest position. 
     
     
       9. The adapter for an airsoft gun of  claim 8 , wherein the projectile inlet is configured for a friction fit with the projectile magazine. 
     
     
       10. The adapter for an airsoft gun of  claim 9 , wherein the projectile outlet comprises a tubular feeder configured for mating with a projectile acceptor in the airsoft gun. 
     
     
       11. An adapter for an airsoft gun, comprising:
 a) a housing comprising a single, integrally formed plastic element, the housing having an upper portion configured to mate with a magazine well of the airsoft gun; 
 b) an air reservoir located within the housing, the air reservoir for holding pressurized gas; 
 c) an air inlet located at a bottom of the housing, the air inlet coupled with the air reservoir and configured for allowing ingress of pressurized air from an attached gas canister; 
 d) an air outlet located at a top of the housing, the air outlet coupled with the air reservoir and configured for allowing egress of pressurized air from the air reservoir to the airsoft gun; 
 e) a piston valve located within the housing between the air reservoir and the air outlet, the piston valve configured for preventing airflow from the air reservoir to the air outlet when in the rest position, and allowing temporary airflow from the air reservoir to the air outlet when contacted by a firing pin of the airsoft gun; 
 f) a projectile inlet located at the bottom of the housing, the projectile inlet configured for allowing ingress of projectiles from an attached projectile magazine; and 
 g) a projectile outlet located at the top of the housing, the projectile outlet coupled with the projectile inlet and configured for allowing egress of projectiles to the airsoft gun, wherein the projectile outlet comprises a tubular feeder configured for mating with a projectile acceptor in the airsoft gun. 
 
     
     
       12. The adapter for an airsoft gun of  claim 11 , wherein the housing is composed of a single, 3D printed plastic element. 
     
     
       13. The adapter for an airsoft gun of  claim 12 , wherein a top of the housing is configured for a friction fit with the magazine well of the airsoft gun. 
     
     
       14. The adapter for an airsoft gun of  claim 13 , wherein the air reservoir is configured to withstand gas pressures of between 120-150 psi.
